MF / HF
MF/HF radio systems operate in the frequency ranges of 300 kHz to 30 MHz and are primarily used for long-range maritime communication. Unlike VHF, which is limited to line-of-sight, MF/HF signals can travel hundreds or even thousands of nautical miles by using ground-wave and sky-wave propagation. These radios support voice communication, Digital Selective Calling (DSC), and data services such as email and weather updates via systems like SailMail or Inmarsat. MF/HF is essential for vessels operating beyond VHF range, ensuring compliance with GMDSS requirements for ocean-going ships.
Furuno FS-2575
The 250 Watt FS2575 MF/HF Radiotelephone with DSC capability facilitates both general and GMDSS communication. It can operate as a DSC transceiver and as a DSC Watch Receiver on all distress and safety frequencies in MF and HF bands. An optional IB585 NBDP terminal can be connected to the transceiver unit for maritime telex operation and distress message/maritime safety information handling. It features a bright, high-contrast 4.3" color LCD (480x272 pixels). Multiple display configurations are available, as well as a Night Mode (white text on black background display) for wheelhouse operation. Instant selection of 256 user-specified channels is provided with a rotary knob or direct keypad input. Quick access to DSC message composition is available by dedicated keys on the control unit. The FS2575 fully meets GMDSS carriage requirements for SOLAS ships operating in A3 and A4 sea areas, as well as ITU recommendation on digital selective calling system for use in the Maritime Mobile Service, ITU-R M.493-13.
